At the time of launching a brand new digital project, it is necessary to have a frequent connection between the engineers and the business team. This is important to make efficient use of time, effort, and resources.
However, one thing that can certainly help is following the right strategy to achieve your objectives. By improving communication between the two professionals, the progress of the project can be prevented from any kind of barriers or bottlenecks.
This is where BDD (behavior-driven development) plays its part. It helps an organization successfully assist its technical team to deliver the software project within the required time frame without getting into much hassle.
What Is BDD ( Behavior Driven Development)?
BDD basically stands for Behavior Driven Development, which is a high-level software project methodology. It uses the outside-in technique in which first we figure out the outside layer that defines the needs of a business.
The most important part of the project is the development phase. BDD is a technique that enables you to make the process easier by breaking up the project into smaller tasks and then concluding with solutions.
Development is a pretty challenging and complicated phase of a project, and resultantly many teams tend to miss the key elements. This vital element of the development process is to fulfill the specific requirements of a business.
To overcome these problems, top software development companies start their development project with a defined approach. The main goals and power of the software development cycle are based on a progressive and defined approach.
How Does Bdd Work
The first step in BDD software testing is to convert the given idea into a list of requirements between the outside and inside layers. Moreover, one crucial fact that is essential to remember while listing the requirements is that it should be so that everyone understands it.
And then, the cycle moves to its next steps. It includes figuring out the requirements and features and fulfilling the given standards to release the final product. What does a company expect to benefit from BDD? Teams who are already using TDD and ATDD consider BDD to drive several benefits.
They expect BDD to offer practical guidance on organizing the communication between different teams of developers, testers, and domain experts. Besides effective communication, tools targeting a BDD approach should automatically generate technical information.
To ensure that every team member gets the point, we accomplish flexibility with a story-driven implementation. This story will act as a natural language that everyone understands and clearly describes the desired outcome.
BDD Vs. TDD Vs. ATDD
| Parameters | BDD | TDD | ATDD |
| Definition | A developmental approach that mainly focuses on the behaviors of the system. | A developmental approach that primarily focuses on the implementation of software features. | A technique that is used to focus on defining the most accurate requirements. |
| Participants | Developers, QAs, and Customers | Developers | Developers, QAs, and Customers |
| Language | Simple and understandable native language | Testing language of the utilized programing language | Simple and understandable native language |
| Main Focus | Knowing and understanding requirements | Unit testing | Defining the criteria for acceptance |
| Implementation Level | High-Level | Low-Level | Low-Level |
| Development Stages | Feature discussion, coding, creating scenarios, testing, refactoring | Refactoring, coding | Testing, coding, learning, and feedback |
| Input Documentation | Requirement documentation, acceptance criteria | Requirement documentation | Requirement documentation |
Why BDD is the Better Approach
It applies the “Five Whys” principle to every proposed user story. Thus ensuring that purpose is clearly related to business outcomes.
Defining “From the Outside in” means implementing those behaviors that contribute directly to the business outcomes.
Explains the behaviors in a single notation that is directly accessible to project domain experts, testers, and developers. It ensures efficient collaboration between the team.
Moreover, implementing these techniques all the way down to the lowest levels of abstraction of the software encourages us to pay attention to the distribution of behavior. Consequently, the progression of the project remains cheap.
However, it’s fair to say that Behavior Driven Development (BDD) is quite familiar with the TDD but differs in a way that focuses on the discussion among team members.
Examples of BDD Testing Frameworks
If you ever consider, “what is bdd framework?” It generally depends on some specific requirements of the organization. These frameworks can best support your applications and have a positive impact on how your teams might operate. Here are some of the most common examples of the BDD frameworks:
- Quantum
- Cucumber
- SpecFlow
- Gherkin
- JBehave
Here is a basic breakdown of how these frameworks are likely to work:
